Photovoltaic Solar Energy. Photovoltaics is a form of renewable energy that is obtained from solar radiation and converted into electricity through the use of photovoltaic cells. These cells, generally made of semiconductor materials such as silicon, capture photons of sunlight and generate electrical current.
Solar photovoltaic is an elegant technology which produces electricity from sunlight without moving parts. In a photovoltaic cell, sunlight detaches electrons from their host silicon atoms.
Photovoltaic modules: a photovoltaic system captures the energy radiated by the sun thanks to the use of special components called photovoltaic modules that is able to produce electricity when hit by sunlight. Support structures of the modules: these structures support the modules by fixing them to the roof the case of flat roofing, support
